I Became a Necromancer Sealed for 1000 Years

In the MMORPG ‘Tower of Avalon,’

I, who possessed a necromancer vampire, was betrayed and schemed against by the protagonist’s party.

Deceived by their lies, I was bound in iron chains and sealed in the deepest, lightless dungeon for an eternity.

After a millennium of gnashing my teeth in anger and betrayal,

On the thousandth year, the seal was finally broken.

Now, all that remains for me is an overwhelming desire for revenge.
